[sane-devel] scanbd Canon MG6250

[Rolf Bensch]

Hi Matthias,

Please (1) activate debug messages with 'export SANE_DEBUG_PIXMA=11',
(2) push one of your scanners's buttons and
(3) read the button status with 'scanimage -A'.

You should receive something similar like this:

...
  Buttons:
    --button-update
        Update button state
[pixma] INTR T=1.580 len=32
[pixma]  00000000:00 10 00 00 00 00 00 00  00 00 00 00 00 00 00 00
[pixma]  00000010:00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00
[pixma]
    --button-1 <int> [1] [read-only]
        Button 1
    --button-2 <int> [0] [read-only]
        Button 2
    --original <int> [0] [read-only]
        Type of original to scan
    --target <int> [1] [read-only]
        Target operation type
...

If you get lines with [pixma], please repeat this test ((2) & (3)) with
all buttons and provide the output from all buttons. Please write the
name of the button to the corresponding debug output.

If you don't get lines with [pixma], Sane doesn't receive the USB
interrupt from your scanner and I need to prepare a patch.

Cheers,
Rolf
